Ke hōʻike nei nā mea ʻenekinia i nā ʻāpana Alloy 4-ʻoi loa no nā pamu hydraulic, nā kiʻekiʻe kiʻekiʻe kiʻekiʻe, a i ʻole nā pūnaewele aila a me nā kinoea waho-ʻaʻole lākou e kauoha wale i nā ʻāpana. Pili lākou i ke kūpaʻa dimensional ma lalo o ke kaʻa kaʻa wela, ka microstructural integrity ma hope o ka mālama ʻana i ka wela, a me ka hoʻololi ʻole ʻana o ka batch-to-batch i ka pane ʻana o ka cobalt-nickel alloy. ʻO ia ke kumu ʻaʻole ʻo "Alloy 4 factory" he huaʻōlelo hulina maʻamau-he kānana. A ma Qingdao, hoʻokahi hale e hoʻomaʻemaʻe mau iā ia: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
No ke aha e koi ai ʻo Alloy 4 ma mua o ka hoʻolei ʻana a i ʻole ka mīkini
Alloy 4—i ʻōlelo pinepine ʻia ʻo AMS 5387 a i ʻole T800-grade cobalt-based superalloy—ʻaʻole i hana ʻia e like me 304 stainless. Piʻi ka wikiwiki o kāna hana ma hope o 10% deformation. Aia kona hoʻoili wela ma ~12 W/m·K—emi iho ma mua o ka hapalua o ka alumini. Kūkākūkā nā ala hana maʻamau. E hoʻoheheʻe ʻia nā mea hoʻoluʻu maʻamau ma mua o ka pau ʻana o ka wela. Ua ʻike mākou i nā hale kūʻai e ʻoki ana i ka 60% o nā hale cylinder holo mua no ka mea ua hoʻohana lākou i nā mea hoʻokomo carbide i helu ʻia no Inconel 718, ʻaʻole ʻo AMS 5387 ʻoi aku ka pale abrasive abrasive.
ʻO ia kahi e pono ai ka hoʻohui kūʻokoʻa - ʻaʻole ma ke ʻano he jargon kūʻai aku, akā ma ke ʻano he pono physics. Ma QINGDAO QIANGSENYUAN, ka hoʻolei ʻana, ka mālama ʻana i ka wela, a me ka multi-axis CNC ma lalo o hoʻokahi hale. ʻAʻohe lima lima, ʻaʻohe puka mōʻaukala wela. Ke hoʻouna ka mea kūʻai i kiʻi kiʻi no ka nozzle cobalt alloy me ± 0.005 mm GD&T callouts ma nā ʻili liʻiliʻi o loko, hōʻoia ka hui i ke kahe o ka palaoa *ma mua o ka ninini ʻana—a hoʻoponopono i ka hoʻolālā mīkini e pili ana i ka paʻakikī like-cast (ʻaʻole nā awelika pepa kikoʻī). ʻOki kēia i ka hana hou mai nā pule a i nā hola.
ʻEhā mau mana e wehewehe i ka Alloy maoli 4 mākaukau
ʻAʻole paʻa nā hale kūʻai metala pololei i ka Alloy 4 me ka hilinaʻi. Eia ka mea e hoʻokaʻawale ai i ka hiki i hōʻoia ʻia mai nā koi brochure:
- Hiki ke hoʻopaʻa ʻia a hiki i ka hoʻoheheʻe ʻana: Ke lawe nei kēlā me kēia billet T800 i nā hōʻike hoʻāʻo wili piha—carbon, cobalt, chromium, tungsten, a me boron maʻiʻo i hōʻoia ʻia me ka ASTM B575. ʻAʻohe mea hoʻololi "kūlike hōʻoia".
- ʻO ka hoʻoponopono ʻana i ka wela: ʻAʻole holo ʻia ka hoʻoheheʻe ʻana i ka hopena ma 1175°C ±5°C i loko o kahi kapuahi kaʻawale ma waho o ka pūnaewele. Hoʻokaʻina pololei ʻia ma hope o ka hana ʻana i ka mīkini paʻakikī, me nā helu hoʻoluʻu i hoʻopaʻa ʻia i ka geometry ʻāpana hope loa - koʻikoʻi no ka pale ʻana i ka embrittlement sigma phase i nā flanges hale pamu.
- Hoʻopau paʻa CMM: Ua hōʻoia ʻia nā ʻae OD/ID hope loa ma nā hale pahu pahu piston pump me ka hoʻohana ʻana iā Zeiss CONTURA G2 CMMs—me nā ʻimi i uku ʻia i ka mahana i hoʻopaʻa ʻia i kēlā me kēia lā. ʻAʻole "nānā ʻia ka laʻana." ʻO kēlā me kēia ʻāpana.
- Ka hōʻoia hana ma mua o nā ana: ʻAʻole i hoʻokuʻu ʻia kahi plug cobalt alloy a hiki i kona hala ʻana i ka hoʻāʻo ʻana i ke kaomi hydrostatic ma 1.5x kaomi hana no 30 mau minuke-ʻaʻohe leki, ʻaʻohe deformation plastic. Nānā nānā ʻike no nā micro-cracks ma lalo o 10x magnification.
Kahi e hāʻule ai nā mea hoʻolako maʻamau—a pehea e lanakila ai ka hoʻokō maʻamau
Manaʻo kekahi poʻe kūʻai "Alloy 4 = kaʻina like me Hastelloy C-276." hewa. ʻO nā mīkini Hastelloy me nā meaʻai ikaika; Koi ʻo Alloy 4 i ka haʻahaʻa-RPM, ka mana spindle kiʻekiʻe-torque a me ka hoʻoheheʻe ʻana i ka nitrogen cryogenic. Ua loaʻa iā mākou kahi kauoha wikiwiki no AMS 5387 ʻōwili pahu waena no kahi winch kaʻa ʻenehana—ua hoʻāʻo ka mea kūʻai aku i ʻekolu mea kūʻai. ʻAʻole i pau i ka pau ʻana o Ra <0.4 µm koi ma hope o ka wili ʻana. ʻO kā lākou hewa? Ke hoʻohana nei i nā huila alumina. ʻO ka hoʻonā? ʻO nā huila vitrified i hoʻopaʻa ʻia ʻo daimana me 150 m/s ka māmā holo ʻokoʻa a me ka lole huila manawa maoli—i hana ʻia i loko o ka hale.
ʻAʻole kēia he manaʻo. Hiki ke hana hou. Hāʻawi ke kaʻina hana lean o QINGDAO QIANGSENYUAN i hoʻokahi ʻenekinia mai ka loiloi ʻōlelo ma o ka lawe ʻana. Loaʻa i kēlā kanaka ka wehewehe GD&T, e hōʻailona ana i ka hoʻopilikia ʻana ma waena o ke kihi noho o ka valve a me ka hoʻolei ʻana i ke kiʻi - ma mua o ka hoʻomaka ʻana o ka mea hana. ʻAʻohe silo. ʻAʻole "ʻaʻole ia kā mākou ʻoihana." Hoʻokahi wale nō ala mai ka sketch a hiki i ka mea i hoʻopaʻa ʻia.
He aha ke ʻano o ka "Reliable" i ka hoʻomaʻamaʻa - ʻaʻole nā ʻōlelo hoʻohiki
ʻAʻole pili ka hilinaʻi i ke koi ʻana i ka ISO 9001. ʻO ia e pili ana i ka hāʻawi ʻana i 127 cobalt alloy nozzles no kahi module control subsea subsea i ka manawa, me nā palapala hōʻoia piha, nā hōʻike dimensional, a me nā lāʻau hoʻāʻo kaomi-a me ka hoʻonohonoho hou ʻana o ka mea kūʻai aku i loko o 48 mau hola no ka mea pono nā ʻāpana ʻole i ka hoʻoponopono kahua.
Ke hana nei ʻo ia i 210 mau kumu pahū kila kila no nā mea kanu desalination ʻo ʻAsia Hema—ʻo kēlā me kēia me ka weld prep grooves i mīkini ʻia i ±0.15 mm—me ka mālama ʻana i ka ≤2% scrap ma waena o 18 mau pūʻulu.
Ke kākoʻo nei ʻo ia i nā hui R&D me nā prototypes wikiwiki: 72-hola ʻōlelo, 10-lā ʻatikala mua, piha FAI hōʻike-me nā ʻāpana metallurgical e hōʻike ana i ka spacing lima dendrite i nā hale hoʻokele waiwai.
Inā pili kāu papahana aʻe i ka Alloy 4—a i ʻole AMS 5387, T800, a i ʻole kekahi ʻano like ʻole cobalt-nickel e koi ana i ka ʻae ʻole i ka hana—ʻo ka pono. Hale hana huila 4 ʻaʻole e hālāwai wale i nā specs. E manaʻo ana ia i nā ʻano hemahema āu i hoʻohālike ʻole ai. ʻO ia ka ʻokoʻa ma waena o kahi mea hoʻolako a me kahi hoa.
